Granny Flat of the Month

Granny Flat of the Month
Mick and Di  wanted to make their big sloping yard generate some return. The result was a neat 50m2 Granny Flat that is now rented under a scheme that guarantees their return 52 weeks a year and pays all maintenance costs. Those smiles say it all.

Granny Flats are affordable housing

Australia has been judged by many as the most expensive housing in the world. The sheer size of our houses, often twice the size of a European equivalent, means simply they cost more to build. Really, the best way to reduce the cost of building a house is to build a smaller quality house.

Smaller housing is smarter housing and it will be our pleasure to help you build a great smaller home for your special purpose.
